53. Determine if y=x^2 is a function.

i think the answer is yes, but can someone explain to me why it's yes, and how you find out if it's a function or not.

I know that for every value of x there should be one value of y, but how do you figure that out in a problem like this?

    for any x, you get a specific y. It is a function. Now for any x, you get more than one y, it is not a function.

  2. y912f

    So, this one is a function..? because for x you get only one y

  3. bobpursley

    Yes, if any x maps to one specific y, it is a function.
